"Oh my God, it is so upsetting!" she told Ellen. "When I ask women […] they're like, 'Oh, you're going to love this.' And I'm like, 'Oh were you sick?' And they're like, 'No.' And I want to hit all of them with my car. I vomit a good dozen times a day. It's bad. I vomited before coming out here."

She continued: "I'm not even kidding; it's so bad. It's so bad. I know, it's so gross. And that's the thing, too -- you're not attractive when you're pregnant. Everybody tells you you glow and your hair is pretty and your nails are pretty. That is total crap. My nails are short, my hair still falls out … it's not all lush and beautiful. And I have no glow. Unless it's like something left over from a bad throw up. It's horrible."

Being 11 weeks into her pregnancy, the American Idol winner noted how many pregnant women don't experience this much sickness. "Every freaking woman I talk to there's maybe one out of every 20 that's like, 'Yeah, I was sick for a week,' and I'm like [laughs] 'OK,' " said Clarkson.
